Water ReuseOctober 22, 20268 min readPowdered activated carbon is a dosing and solids-management decision as well as an adsorption decision. Procurement should establish which contaminants are targeted, how the selected carbon performs in the real wastewater and how the added particles are captured before water is released.

Engineering & ProcurementOctober 22, 20268 min readOn-site hypochlorite generation changes the chemical-supply boundary of an industrial water plant. The enquiry needs to cover salt and water quality, electrical duty, hydrogen management, product storage and continuity of disinfectant delivery through planned and unplanned generator outages.
Read ArticleWater ReuseOctober 22, 20268 min readUV and hydrogen peroxide advanced oxidation should be evaluated against named contaminants and the actual industrial water matrix. A defensible purchase connects treatability testing, optical conditions, oxidant delivery and residual management with the requirements of the downstream reuse process.
Read ArticleWater ReuseOctober 22, 20268 min readA blower package should satisfy the biological oxygen requirement through the actual diffuser and basin system over its operating range. Nominal air capacity is insufficient without a common air reference, pressure envelope, minimum mixing requirement and a workable duty-and-standby control sequence.
Read ArticleWater ReuseOctober 22, 20268 min readIndustrial sludge decanter selection requires a common trial basis for cake, liquid clarity and loading. Bowl speed, scroll differential speed and torque interact with feed variation, so the enquiry should cover operating control and the returned centrate as carefully as the discharged cake.
Read ArticleWater ReuseOctober 22, 20268 min readA rotary drum screen should be purchased against the debris and hydraulic conditions it will actually encounter. Aperture geometry, available head, cleaning utilities and the route for retained screenings determine whether the package protects downstream industrial wastewater equipment.

Water ReuseOctober 22, 20266 min readA customer from Kenya visited the Jiangsu branch of BHP Water Treatment to review MVR evaporator technology for water treatment projects. The session covered the MVR evaporation and concentration system design scheme, the equipment specification table and open technical discussion with the BHP engineering team.

UltrafiltrationOctober 21, 20268 min readLow-range turbidity monitoring should distinguish a change in filtrate from a change in the sample path or optical condition. The purchase needs an agreed measurement method, representative sampling and a practical way to investigate bubbles, deposits and instrument faults.

Reverse OsmosisOctober 21, 20268 min readResidual chlorine monitoring before RO is an instrument and sample-system decision. The selected measurement must match the oxidant risk, and the installed response must account for sample transport, analysis time and the action taken when the signal is unavailable.
Read ArticleWater ReuseOctober 21, 20268 min readA polymer preparation package must deliver usable flocculant solution when the downstream process needs it. Matching a tank volume to a dosing flow is insufficient unless wetting, maturation, solution age and the chosen polymer grade are also defined.
Read ArticleWater ReuseOctober 21, 20268 min readAn industrial sludge screw press enquiry should connect feed variability, floc conditioning and the destination of both cake and filtrate. A wet-volume capacity alone cannot establish the solids-processing duty or the usefulness of the resulting dewatered material.

Water ReuseOctober 21, 20268 min readA hydrocyclone or centrifugal separator should be selected from particle behaviour and a defined hydraulic range. It can be a useful grit-removal stage, but a nominal connection size or a clear-water test cannot establish performance on mixed industrial solids.
