UltrafiltrationOctober 15, 20269 min readA UF membrane integrity testing package needs more than a compressed-air connection and a pass lamp. Its valves, instruments, test boundaries and records must support a manufacturer-approved method. Define that package during procurement so operators can distinguish a valid membrane test from a failed setup, an external leak or an interrupted sequence.

Reverse OsmosisOctober 15, 20268 min readAn industrial RO membrane pressure vessel is a mechanical pressure boundary as well as a membrane housing. Selecting it by diameter and headline pressure alone leaves important interfaces unresolved. Buyers should agree the operating envelope, element connections, support arrangement and replacement space before the skid layout and purchase order are released.

Water ReuseOctober 15, 20266 min readBHP Water Treatment took part in the 2026 China Power Battery Recycling Industry Conference in Ganzhou, Jiangxi Province, China, on 15-16 October 2026 and joined the new member unit plaque presentation of the Battery Recycling Committee of the China Electronic Energy Saving Technology Association.

Engineering & ProcurementOctober 14, 20268 min readA filter press for industrial wastewater sludge should be selected from measured solids loading and representative dewatering tests. Sludge volume, chamber volume and advertised cake dryness are different quantities. A useful procurement specification connects them through the complete operating cycle, conditioning requirements, filtrate route and the site's practical cake-handling arrangement.

Engineering & ProcurementOctober 14, 20268 min readAn industrial wastewater pH neutralization system needs more than a pH setpoint and two dosing pumps. The design should connect representative chemical-demand tests with tank duty, mixing, reagent delivery and a verified release decision. Similar inlet pH readings can correspond to very different treatment requirements when wastewater composition and buffering differ.

Pure WaterOctober 14, 20268 min readConductivity measurement can support industrial pure-water quality control only when the sensor, temperature basis, installation and release logic are specified together. A display with extra decimal places cannot correct the wrong cell range or an unreliable sample path. Define what the measurement will prove and what other quality evidence the application still requires.

Reverse OsmosisOctober 14, 20268 min readA multimedia filter quotation should explain how the selected vessel and media will handle the measured feed solids and how the bed will be backwashed at the site. Nominal service flow is insufficient when wash water, drain capacity or production continuity is undefined. Treat filtration, backwash and return to service as one equipment duty.

Reverse OsmosisOctober 14, 20268 min readAn industrial RO high-pressure pump must match a membrane system across its actual operating envelope. A quotation based on one flow and one pressure can hide problems at cold-water duty, reduced production or low suction pressure. Define the hydraulic cases, control responsibilities and acceptance evidence before comparing pump brands or motor ratings.
Read ArticlePure WaterOctober 13, 20269 min readAn industrial pure-water UV reactor should be selected from a defined microbial-control duty and a documented operating envelope. Flow, UV transmittance, lamp condition, reactor hydraulics and sensor evidence all matter. Specify how inadequate treatment is detected and how affected water is handled, then verify the installation with an acceptance plan suited to the actual manufacturing application.
Read ArticleReverse OsmosisOctober 13, 20269 min readDechlorination should be specified as an oxidant-removal duty with measurable protection at the industrial RO inlet. Activated carbon and bisulfite dosing create different maintenance, monitoring and failure-management requirements. Select between them using the actual disinfectant species, feed-flow range, downstream membrane limits and the site's ability to operate the chosen barrier consistently.
Read ArticleReverse OsmosisOctober 13, 20269 min readA final cartridge filter is often a small item in an industrial RO quotation, yet its retention rating, pressure loss and sealing arrangement affect the protection available to the membrane train. Specify the cartridge and housing as one assembly. Include how operators detect restriction, replace cartridges and confirm the filter has returned to service correctly.
Read ArticleReverse OsmosisOctober 13, 20269 min readA duplex softener can maintain a softened-water supply while one vessel regenerates, provided the resin capacity, valve arrangement and regeneration time suit the real operating cycle. Specify the hardness duty and acceptable leakage first, then verify that the standby vessel is genuinely ready when changeover occurs. Two tanks alone do not establish continuous availability.
