All RO systems produce a concentrated reject stream and understanding the ionic composition and behaviour of the species in the fluid is the key to successfully optimising the plants long term performance and efficiency.

 

The addition of an antiscalant in the feed water inhibits the formation of mineral scale forming species in the reject stream.

 

The following information is required to enable projections to be carried out:

  • Water analysis including pH and temperature

  • Operational Parameters, such as flows and recovery

  • Any pre-treatment

  • Membrane type ( for rejection characteristics)

 

If you require design projections please to enter your details and our sales team will contact you to discuss your particular requirements.

Selecting the correct pump for the operating environment and duty point are key factors in ensuring efficient, reliable long term pump performance.

 

Desal Supplies can use their training and experience and Danfoss' software program to accurately select the correct pump for your application.

 

If you require assistance with pump sizing please  to enter your details and our sales team will contact you to discuss your particular requirements.

 

The iSave is the first fully integrated energy recovery device specifically designed for reverse osmosis plant applications, it incorporates isobaric pressure exchanger, booster pump and electric motor as a single unit.

 

The benefits of the iSave are compact design, easy installation, increased RO plant efficiency and reduced running costs.

 

When the iSave is operated with the APP range of Pumops the iSave selection software accuratley predicts the plant operating conditions, for more information of further assistance please and a member of our sales team will contact you to discuss your particular requirements

 

We can offer a comprehensive approach to pressure system selection

 

The CADIX (Computer Aided Design for Ion Exchange) is a comprehensive ion exchange engineering tool for designing new water treatment systems and evaluating an existing plant performance with DOWEXTM ion exchange resins.  

 

Cadix allows design of both co-flow and counter-flow regenerated systems for a range of applications.  It is designed for windows and is an easy program to use, but it does assume that the user has some knowledge of an ion exchange resin technology and terminology.

 

The CADIX design program allows users the flexibility to design the whole ion exchange process and it offers 3 core sections:

 

  • New Plant Design - If you are projecting a new ion exchange water treatment plant the option allows a flexible interactive design program.
  • Existing Plant Evaluation - If you are already operating an IX water treatment plant and want to evaluate its potential performanceusing actual operating data.
  • Retrofit - Compares the economics and savings from any currently installed systems

A range of services specifically designed to identify the cause of membrane failure in reverse osmosis (RO), nanofiltration (NF) and ultrafiltration (UF) plants are available, there are three levels of membrane autopsy depending on the nature of the problem and the level of detail you require:

 

Level 1

Deposit/foulant identification

 

Level 2

Deposit/foulant identification

Membrane characterisation - salt rejection and flux

Oxidation & integrity testing

 

Level 3

Deposit/foulant identification

Membrane characterisation - salt rejection and flux

Oxidation & integrity testing

Cleaning tests - identification of optimum cleaning chemical, dosage, contact time and pH for foulant removal

When designing an RO plant there are many different parameters that must be taken into consideration.  System performance is typically characterised by permeate flow and permeate quality where the main goal is to maximise quality and recovery whilst minimising pressure and membrane costs.  

The biggest influence when considering membrane design is the fouling tendency of the feed water, which is caused when dissolved solids and colloidal matter are present in the feed water and are concentrated at the membrane surface.

 

Accurate design is crucial to to getting the most from your water treatment system and Desal Supplies are able to carry out membrane design projections using the ROSA (Reverse Osmosis System Analysis) design software.  From the information you provide we can carry out projections and make recommendations as to which membranes would be most suited to your particular application.
