Hyperscale and colocation data centers consume 3–5 million gallons of water per day per 100 MW of IT load. EnviroBox MBBR modular systems treat cooling tower blowdown, process wastewater, and grey streams to Title 22 / ASHRAE 188 reuse quality — on-site, in 8–16 weeks, at 30–50% lower CAPEX than civil construction.
AI training, cloud compute, and colocation facilities are among the fastest-growing industrial water consumers on the planet. Regulators, investors, and municipalities are forcing data center operators to account for every gallon.
Blowdown concentrates everything in the makeup water by the cycles of concentration (COC). At COC 4×, TDS reaches 2,000–3,000 mg/L, conductivity 1,500–3,000 µS/cm, hardness 400–800 mg/L as CaCO₃, and biocide residuals 0.5–2.0 mg/L. MBBR biological treatment targets organics and ammonia; downstream RO or IX handles TDS for return-to-tower reuse.
California SB 332 mandates industrial water recycling reporting. Virginia DEQ requires data center water impact assessments for new permits. Arizona DWR has imposed moratoriums on new potable groundwater permits in Phoenix metro. EU Water Framework Directive requires best available techniques for industrial users >10,000 m³/day.
Cooling tower blowdown has low, variable organic load — conventional activated sludge is over-engineered and unstable under flow variation. MBBR biofilm is fixed on media, highly resistant to washout, and self-regulating. No return activated sludge required. Modular — size to your actual blowdown volume, expand as campus grows.
Measured performance targets for cooling tower blowdown and mixed data center process streams. Values represent design goals for a 3-stage MBBR system with lamella clarification, polishing, and optional downstream RO.

* Conductivity/TDS reduction achieved via downstream reverse osmosis or ion exchange — not MBBR alone. MBBR targets organics, TSS, and ammonia. Full TDS reduction to <200 µS/cm for return-to-tower reuse requires RO skid integration.
Data center blowdown is characteristically low in organic load but high in TDS, conductivity, and biocide residuals. The EnviroBox DC train is configured specifically for this profile — with pre-treatment, MBBR biological, clarification, UV disinfection, and optional RO for return-to-tower.
EnviroBox DC effluent targets multiple reuse pathways simultaneously. The treatment train is designed to meet the most stringent applicable standard — cooling tower makeup — which subsumes landscaping, toilet flush, and other non-potable uses.

EnviroBox DC-Series systems are designed to meet or exceed the following standards at design conditions. Industrial or complex waste streams may require site-specific treatability studies prior to final design.

EnviroBox DC-Series systems deploy in 8–16 weeks from purchase order for systems up to 1 MGD. Timeline excludes permitting — NPDES and state reuse permits typically require 6–12 months and should run concurrently with fabrication.
