H2O Surplus is a privately owned company that provides pre-owned equipment, refurbished as well as new equipment for water and wastewater plants. We are also the sole distributor in Southeast Asia of the Water-CTI Zero-Liquid-Discharge Cooling Tower Technology.

Our professional staff combined with our sister company (Integrated Design Technology in Oakland, California established in 1984) personnel, has the engineering and manufacturing expertise required to provide high quality and cost effective solutions to water and wastewater treatment concerns for private industry and governmental agencies.

We offer a broad spectrum of services related to engineering design and construction, from conceptual planning to implementation or construction management. Our engineering design capabilities include civil, chemical, mechanical, electrical, instrumentation and controls, structural engineering, automated drafting and cost estimating. Specific services we offer include:

  • Economic and technical feasibility studies
  • Conceptual planning and design
  • Process evaluation and system analysis
  • Detailed engineering design
  • Preparation of construction plans and specifications
  • Preparation and acquisition of permits for construction
  • Computer-aided drafting and design
  • Bid packaging and assistance during bidding
  • Equipment selection and procurement
  • Project scheduling and cost estimating
  • Value engineering and construct ability analysis
  • Construction supervision and contract administration
  • Startup and troubleshooting
  • Preparation of O&M procedures

We offer the above services in projects related to water and wastewater treatment, tank removal and replacement, facility and process modification.

How WCTI Program Works:

  • Proprietary pre-conditioning system removes scale-forming ions from tower make-up
  • Unlimited tower concentrations (10-600X)
  • Soluble silica controlled at 200-800 Mg/L
  • Polymerized silica protects metals at high TDS
  • High TDS and high pH (more than 9pH) prohibits bio and pathogen growth

WCTI ZLD Installation:

  • Tower makeup water simply passes through WCTI pre-conditioning system
  • Water wastage is reduced to 0-5% range
  • No chemical or control systems required
  • Corrosion almost zero and scale risk eliminated with removal of hardness ions from makeup
  • Environmentally friendly / no toxic chemicals
  • Just maintain salt in tank / low usage design

WCTI PROGRAM Benefits:

  • Reduces total treatment cost by 60-70%
  • Ideal corrosion protection (less than 0.1 MPY) for steel, copper, galvanized and aluminium
  • Non-toxic program / eliminates discharge
  • No chemical handling and storage
  • Reduced testing and Operator time
  • Eliminates 'Bleed and Feed' chemistry
  • Eliminates heat transfer loss, thus saving on power consumption

Disadvantages of a Typical Chemical Installation:

  • Must feed acid and inhibitors to reduce water wastage to 10-20% range.
  • Requires control systems for conductivity (blow down), pH acid, inhibitor and biocide
  • Significantly higher corrosion rates and increased risk for scaling with failure of even one of the multiple control systems
  • Chemical handling and storage risks
  • Costly 'Bleed and Feed' Treatment
