Projects and cases
The details of what was actually done on each project — with results and supporting documents.
General Motors Powertrain Uzbekistan
Challenge
The plant needed an independent, objective assessment of its water treatment and cooling systems — free of any reagent supplier's commercial interest.
Approach
A full water audit was carried out using the standard methodology: technical documentation review, on-site measurements, lab analysis of samples, and a final report with recommendations.
Result
The audit was completed, giving the plant an independent assessment of system condition and concrete recommendations. The site ecologist provided a reference letter.
SamAvto
Challenge
The antiscalant in use was not adequately protecting the reverse-osmosis system from scaling.
Approach
Water parameters and the existing dosing scheme were assessed, and a more effective antiscalant matching the system's parameters was selected.
Result
The new antiscalant was confirmed by an official letter from the plant.
AO «NGMK», GMZ-3
Challenge
The plant's water treatment costs were higher than its existing reagent program allowed for.
Approach
More than 10 tonnes of antiscalant, matched to the plant's water parameters and process, were supplied.
Result
Water treatment costs were cut by 15%. The supply was formalized under a contract.
General Motors Uzbekistan (assembly plant, Asaka)
Challenge
The paint shop's recirculating water system needed to reduce fouling of paint booths and drainage troughs caused by overspray paint particles.
Approach
Implemented Nalco APEX treatment — a coagulant bound the paint particles and carried them through the trough system into a settling basin, where a flocculant ensured final settling.
Result
Paint booths stayed clean, laminar airflow was undisturbed, cutting paint defect rates, increasing line throughput, and reducing rework. Treatment cost came to under $1 per body.
A mining and beneficiation plant in Uzbekistan
Challenge
Needed to increase pulp settling speed in the washing section and compare the result against the previously used flocculant.
Approach
Ran comparative lab trials of four flocculants at different dosages, including a test at half the standard dose.
Result
The best-performing flocculant reached a settling rate of 2.30 m/h — 6.2 times faster than the product previously used, and nearly twice as fast even at half the dosage. Industrial trials were recommended.
A large nitrogen fertilizer plant in Uzbekistan
Challenge
Needed to inspect three systems at once — recirculating cooling, waste-heat boilers, and reverse osmosis — including calibrating monitoring equipment and dosing pumps.
Approach
Carried out a full review of all three systems, identifying a flawed antiscalant dosing scheme on the reverse-osmosis unit and an overly lax dissolved-oxygen spec for boiler feedwater.
Result
Delivered a package of 4 concrete recommendations — from tightening the dissolved-oxygen spec with the plant designer to SDI testing and lab analysis of filter deposits.
A nitrogen fertilizer complex in Uzbekistan
Challenge
Needed to service the dosing monitoring system across two shops and identify the cause of a 4-month reagent overconsumption.
Approach
Calibrated the dosing pumps, checked treatment parameters, and analyzed actual reagent consumption — tracing the cause to a pump control program error rather than genuine increased demand.
Result
Gave the plant 4 concrete monitoring and reporting recommendations and corrected the dosing program; the overconsumption is expected to be offset within 3 months without changing the official consumption norm.
