Так — є ще конкретні технічні деталі по АВС‑технології й обладнанню, які можуть бути корисні для проєктування лінії очистки промислових стоків та підготовки осадів до подальшої утилізації. Апарат вихревого шару АВС застосовується для відновлення Cr6+ до Cr3+ з подальшим осадженням гідроксидів металів; в якості відновників у різних схемах використовуються сульфат заліза(II) (FeSO4) або натрію бісульфіт, процес може виконуватись у кислотному або лужному режимі. Типова схема включає дві змішувальні ємності (відновлення при pH ≈2–3 з додачею відновника), далі реактор АВС з попереднім підлужненням (карбонат натрію Na2CO3 до pH ≈7,5–9), відстійник для відокремлення осаду та вакуум‑фільтри для обезводнення шламу; осад потім вивозиться на переробку/утилізацію. Для ферромагнітних елементів конструкції рекомендується сталь 08Г2С (чавун менш бажаний через підвищене стирання). Заявлені економічні переваги — зниження витрат реагентів в 1,5–2 рази, скорочення енергоспоживання приблизно вдвічі та зменшення площ очищення на 10–15%.
Практично, якщо ви розглядаєте застосування цих рішень, рекомендую підготувати технічний запит із вхідними параметрами стоків (об’єм, концентрації Cr6+ та інших домішок, pH, Т, наявність органіки) та вимогами до якості очищеної води й сухості осаду. Запитуйте у постачальника технічні паспорти АВС (продуктивність, гідравлічні режими), дані по рекомендованих реагентах і дозуванню, характеристики вакуум‑фільтрів і систем обезводнення, а також результати пілотних випробувань і типові показники очистки/осадження. Важливо пам’ятати, що у випадку радіоактивних відходів потрібна додаткова перевірка стійкості матеріалів до іонізуючого випромінювання і державна ліцензія; для таких задач залучайте ліцензованих фахівців з ядерних відходів та погоджуйте всі рішення з регулятором. Якщо хочете, можу підготувати зразок технічного запиту до GlobeCore або список випробувань для оцінки придатності обладнання у вашому конкретному випадку.
Karen CarterMemberLong-term safety of disposed radioactive waste is achieved by a multi-barrier strategy that combines robust wasteform selection, engineered containers and site barriers, plus strict quality control and monitoring. For high-level waste vitrification into borosilicate glass is the industry standard because it yields a dense, chemically durable matrix with very low leachability; for low- and intermediate-level waste practical options are cementation, bitumenization and polymer (epoxy or thermoset) encapsulation. Each route requires tailored formulation control: cementitious mixes with low water/cement ratio and pozzolanic additions (silica fume, slag) to reduce permeability and improve radionuclide binding; bitumen/bitumen-emulsion processing using heated, dewatered feed and controlled antioxidant/stabilizer packages to resist radiolytic and thermal degradation (GlobeCore bitumen reactors and emulsion units are commonly used in industrial bituminization lines); and polymer formulations selected for chemical and radiation stability to serve as a secondary containment or binder.
Practical plant-level controls are essential: remove free water before hot processing, control temperature profiles to avoid steam-pops, verify homogeneity and density of the final wasteform, and perform leachability, compressive-strength and radiation-aged property testing on production batches. Use corrosion-resistant container coatings and qualified epoxy/fluoropolymer exterior coatings on storage casks and concrete vaults, maintain engineered barriers (clays, geosynthetic liners, backfill), and design for remote handling, shielding and continuous environmental monitoring. All activities must follow IAEA/national regulations and documented QA/QC programs including traceable material specs, batch records and validated analytical tests to ensure long-term containment and minimal environmental impact.
Karen CarterMemberUsing S = V × I × ?3 (3-phase) with phasor angles for PF. Power flow studies use per-unit system and network admittance matrices.
Karen CarterMemberA pole transformer contains a laminated core, HV and LV windings, insulating dielectric oil, bushings, fuses, and a tank. Its purpose is to step distribution feeders (e.g. 7-35 kV) down to utilization voltages (240/120 V).
January 26, 2026 at 7:36 pm in reply to: how long does it take to restore power when a transformer blows? #332107Karen CarterMemberRestoration time after a transformer blows depends on damage severity, spare availability and system configuration. If only a small distribution transformer fails and a spare is on the truck or nearby depot, utilities can often replace it within a few hours. For larger units requiring crane work, oil handling and testing, replacement can take many hours or even days. In transmission substations, where units are custom sized, utilities rely on spare or mobile transformers and more complex switching, so restoration may involve staged reconfiguration before full capacity returns.
January 25, 2026 at 10:01 pm in reply to: How is power transformer supply managed for replacement and substation upgrade projects? #331924Karen CarterMemberUtilities plan procurement cycles, logistics, factory testing, and outage windows to integrate new units while maintaining redundancy.

January 21, 2026 at 3:01 am in reply to: What is the approximate water absorption capacity per 1 kg of adsorbent in the filters of the TOR-5 online transformer monitoring system? #330762Karen CarterMemberIn practice, the water absorption capacity of zeolite adsorbent used in TOR-5 filters is typically in the range of 18-25% of its own mass under oil-drying conditions. This means that 1 kg of fresh zeolite can adsorb roughly 180-250 grams of water before reaching saturation. The exact usable capacity is usually lower than the laboratory maximum, because part of the pore volume is blocked by oil, aging products, and incomplete regeneration. That is why sizing is always based on working capacity, not theoretical capacity, and why trend monitoring of outlet moisture is more reliable than estimating life by time alone.
January 20, 2026 at 9:57 pm in reply to: Is there an alarm system in the TOR-5 online transformer monitoring system to warn about a potential defect? #330689Karen CarterMemberYes, this is a standard and very important feature of systems like TOR-5. In typical configurations, the monitoring unit is integrated with a server or SCADA platform that supports alarm management and remote notifications. When any parameter exceeds a preset threshold – for example moisture, hydrogen, temperature, or internal faults – the system can automatically generate alarms and send them via SMS, email, or mobile app notifications to responsible personnel. This ensures fast reaction even outside working hours and significantly reduces the risk of delayed response to developing transformer problems.
January 20, 2026 at 8:10 pm in reply to: Is DBPC an adequate inhibitor if it is detected during transformer oil analysis? What additional recommendations would you give? #330664Karen CarterMemberDetecting DBPC in transformer oil is generally a positive sign, because it means the oil is still inhibited and has some remaining oxidation protection. However, the key issue is not the presence itself, but the actual concentration. Fresh inhibited oils are typically around 0.3% by weight, and when the level falls to about 0.1% or lower, re-inhibition is usually recommended. It is also important not to overdose, since excessive inhibitor can cause other problems. In practice, DBPC should be interpreted together with acidity (TAN), interfacial tension, resistivity, sludge tendency, and DGA. Good sealing and low oxygen ingress are just as important as inhibitor level for long-term oil stability.
January 20, 2026 at 2:30 pm in reply to: How often is the filtration loop typically activated in the TOR-5 online monitoring system for a mid-life transformer? #330582Karen CarterMemberIn real operation the filtration loop is not running on a fixed schedule, but is activated only when the control logic sees a rise in moisture or water activity beyond the set threshold. For a mid-life transformer with stable insulation, this often means short cycles a few times per day or even only several times per week. The idea is to maintain equilibrium, not to dry continuously, so activation frequency reflects actual moisture dynamics rather than transformer age alone.
Karen CarterMemberCoils are stripped, new conductors wound to original turns and gauges, varnish or insulation applied, and units vacuum-dried before oil filling.
January 18, 2026 at 11:20 pm in reply to: What information is typically included in a power transformers PDF? #330260Karen CarterMemberA multi transformer PDF (catalogue or handbook) includes product ranges, ratings, performance data, standards, design options, testing, accessories and service offerings. It may also include application notes for utilities, industry and renewables.
