Our Technologies

Desalination Systems

We specialize in the design and manufacturing of membrane systems, specifically in Reverse Osmosis (RO) processes, for different purposes: drinking water, water for irrigation, process water production, industrial and wastewater reclamation, among others.

Reverse Osmosis is a technology in which pressure is applied on a semi-permeable membrane, allowing for the passage of water while rejecting soluble salts.

RO membranes can treat a various range of salinities, from tap water, brackish water to seawater. Considering the differing water qualities and flow rates, each system is tailor-made, where the pre-treatment, the RO system and post-treatment, are specifically customized to the client’s needs.

We take into consideration that desalination processes are highly energy- consuming due to the high pressures that must be reached, and therefore the systems are designed to be energy efficient. In seawater desalination, for example, the pressure must reach as high as 60-70 bars. In that case, energy recovery devices are employed, which reduces the energy consumption by 40 percent.

Smart Clarifier System

The Smart Clarifier System includes an advanced control program that automatically injects chemicals accordingly to inlet flow and turbidity.

The control system calculates the amount of sludge entering into the clarifier and respectively determines the frequency of sludge removal.

Sensors are installed above the tube settlers providing online monitoring of the water quality in the various stages of the process in order to optimize the dosage chemicals

Sludge settles are located at the bottom of the clarifier and the sludge is discharged through perforated pipes laying in concrete tunnels. The actuated valve is installed at the end of every pipe, opening the valve causing the sludge to discharge towards the sludge lagoons.

Sludge management system – To increase dramatically the overall recovery rate of the system.


  • Easy to operate and maintain
    • No moving parts in the clarifier
    • Fully automated operation
    • Minimal operator intervention
  • Safeguard the treatment quality due to the use of tube-settler modules – homogenous distribution of raw water on the clarifier’s surface
  • Due to the Smart Control System, chemicals and energy consumption levels are extremely low
    • Energy consumption is about 0.1kWh/m3
    • The total estimated OPEX is usually less than 3.0PHP/m3

Demineralization Systems

We provide demineralization systems to produce ultrapure water. Ultrapure water, also known as “UPW” or “high-purity water,” is water that has been purified to uncommonly stringent specifications. Ultrapure water is mainly used in the semiconductor, pharmaceutical and power plant industries.

Ultrapure water contains by definition only H20, H+ and OH- ions in equilibrium.
Therefore, ultrapure water conductivity rate is about 0.054 µS/cm at 25oC which is also expressed as resistivity of 18.3mΩˑcm.

Demineralization systems consist of the following stages:

  • Pre-treatment – with multi-media filters or UF membranes, chemicals injection, cartridge filters
  • Double-pass reverse osmosis (RO)
  • CO2 removal with degassing towers or gas transfer membranes
  • Final ion removal with Electro-deionization (EDI) or mixed bed resins

What is electro-deionization?

Electro-deionization is a process in which ions pass through a selective membrane when the motive force is an electrical field.

Ion Exchange

Ion exchange is an exchange of ions between a solution and a resin. Resins are polymeric beads that are site specific and can bond with different groups, such as anions, cations, or it can be selective to one substance.

Ion exchange columns are frequently used for water softening and Ultrapure Water polishing.

Wastewater Treatment

Municipal and some of the industrial wastewater are rich in Total Suspended Solids, organic matter, Nitrogen and Phosphorus. These substances are considered as contaminants and must be eliminated for water recycling or discharge to the environment. Biological treatment is the most efficient and cost-saving way of treating wastewater.

Wastewater treatment plants usually employ the following stages:

  • Screening, grit and sand removal, grease and fat removal
  • Primary sedimentation
  • Biological treatment (secondary treatment) – including anaerobic, aerobic and anoxic stages.
  • Secondary clarifier
  • Tertiary treatment including depth filtration and disinfection.
  • Sludge treatment – sludge digestion and dewatering

There are different configurations for wastewater treatment plants. The most common is conventional activated sludge, which is a continuous process for relatively large plants.  A wastewater plant can also work in a batch mode in a process called Sequencing Batch Reactor (SBR). For relatively low flow rates, more advanced technologies are employed. One technology is Membrane Bioreactor (MBR) that can treat highly organic content. In this technology, the effluent is filtered with ultrafiltration membranes. Another technology is Moving Bed Bioreactor (MBBR) in which the biomass is grown on carriers for very efficient treatment.

Filtration Systems

Depending on the inlet turbidities, filtration can take place with or without a clarifier. Multi-media filters remove particles by size or by special media with affinity to a specific group (such as Arsenic, Manganese, Iron etc.).

Sand filtration is based on depth filtration, in which the suspended particles adsorb on the sand under applied pressure. Those filters can be cleaned with simple backwash procedure.

Another proven and reliable technology to reduce turbidity is the use of Ultrafiltration membranes. These membranes can reduce the turbidity to under 0.1 NTU.

Anaerobic Treatment

Industrial wastewater contains a high concentration of pollutants, such as organic material and suspended solids.

On one hand, pollutants harm the environment, but on the other hand they are brimming with energy potential.

We have the solution to solve the environmental problem, while at the same time converting pollutants into steam or electricity.

There are three main options for anaerobic digestion:

  • Low Reaction Rate
  • EAL – Engineered Anaerobic Lagoons
  • Medium Reaction Rate
  • CSTR – Completely Stirred Tank Reactors
  • High Reaction Rate
  • UASB – Up-flow Anaerobic Sludge Blanket
  • EGSB – Expended Granular Sludge Bed

Standard Systems

Designed to produce low conductivity water from a tap or well water, these systems use state-of-the-art reverse osmosis membranes. The permeate is used in various applications, such as boiler feed, municipal, water reuse, food processing, bottling, semiconductor, and a wide variety of other applications. Series WM-B systems use 40″ long membrane elements with an 8″ diameter.

Pressure vessels contain multiple elements and are mounted in a horizontal position.
