Custom Purification

Custom Water Treatment Systems

Since we understand that in most cases, one standardized water treatment system will not incorporate the issues all of our customers have. We have implemented the expertise of our engineering team to design tailor-made solutions that can handle the unique water quality issues existing in any application.

Problems regarding sizing compatibility, or certain pollutants, we have the experience and proven track record to produce a water treatment system that will address all of your issues. The following information will give you insight on some of the specific challenges that we have dealt with and straightened out:

Questions & Answers

What is the process of water purification?

Pure Aqua’s team of engineers work round the clock to remove bacteria, viruses, and other micropollutants from your drinking water. Our water purification systems treatment process begins at our production facility. In this location, we build reverse osmosis systems that are designed to remove sediments and particles from unfiltered water such as seawater, brackish, or tap water. These systems are combined with chemicals such as chlorine to dissolve heavy metals into physical configurations, which will allow the filters to permeate through the water. The result is an output of pure, potable water.

How we engineer our water treatment systems?

Our engineering process consists of important factors that we take into consideration to build our water purification systems. Here are some of these considerations:

  • Thorough water analysis: Our engineers design systems specific to each customer’s requirements with a detailed water quality report.
  • Environmental considerations: With a completed water analysis, our team will design a system to meet the demands of our clients operating environment. This includes available utilities, local climate, facilities, and site accessibility.
  • Serviceability: Not only are our systems engineered to meet the operating requirements of the job, our engineers strive to design equipment with easy serviceability in mind.
  • Parts: Our systems are designed using industry-standard components, most of which are readily available in most regions.

Your projects are supervised by Pure Aqua Engineers throughout the life of the project.
