Tips And Tricks To Help You Purchase The Best Demineralization System.

Potable water is a common denominator in virtually all industrial, commercial and residential applications. However, respective applications necessitate varying grades of potable water. Demineralized water is a distinct form of purified water commonly utilized in complex industrial and commercial applications such as pharmaceuticals, microelectronics, and laboratories.

To sufficiently gratify the qualitative and quantitative demands of industries reliant on deionized water, we manufacture highly customized demineralization systems. Our most productive deionization systems exploit established demineralization technologies such as ion exchange, electrodeionization, and reverse osmosis.

Having a plethora of options is great but it can give you a selection headache. This means that you should carry out extensive background checks to ensure you settle for the perfect system. Procuring the wrong demineralization system can bring detrimental financial and operational losses. The underlying article utilizes data from our auspicious experts to help you purchase the perfect demineralization system.

Factors to Consider Before Purchasing a Demineralization System.

Before venturing into the market to procure a demineralized water plant you should first figure out the specifications and requirements of your respective application. For example, you should understand the quality and quantity of deionized water needed before procuring any deionization equipment. Here are some of the dynamics you should keep a close eye on before procuring your demineralization system.

• The Composition and Concentration of Your Inlet Water.

Inlet water is commonly referred to as feed water. It is the untreated water fetched from taps, wells, rivers, oceans, or streams that are subsequently treated to produce purified water. Before purchasing a demineralization system, it is paramount that you establish the harbored contaminants and their respective concentrations.

This can be accomplished by testing samples of the feed water. A comprehensive water test will indicate the water’s conductivity, resistivity, microbial count, TDS level, TOC level, and TSS level. This will help you determine the kind of demineralization system that would best suit your application as well as the appropriate pretreatment system.

• The Required Quality of Demineralized Water.

Demineralized water can be differentiated based on quality. Certain applications such as pharmaceuticals and laboratories have stringent quality demands when it comes to deionized water. Others are not as stringent hence it is important to understand the respective quality demands of your application.

If your application necessitates the highest grade of demineralized water, a reverse osmosis di water system or a reverse osmosis EDI water system would be very handy. After establishing the required water quality, you can proceed to consult our technicians, who will aid you select the perfect deionization system.

• The Average Quantitative Demand.

Having a water deionizer system that gratifies your quantitative demands is equally important as having a system that produces high-quality demineralized water. Establish the operational scale of your application to determine the exact number of deionized water gallons you will need per day. This will help you choose a demineralization system whose size and production capacity bodes well for your enterprise.

• The Imminent Operational Costs.

Budgeting in advance using rough estimates helps you manage your finances better and mitigates the premature closure of projects due to insufficient funds. Before procuring a demineralization water system, do background checks to establish the projected purchasing prices as well as the respective costs of operation and maintenance. To come up with accurate operational cost projections, keep a close eye on the following parameters.

Feed Water.

If you get your water from your respective municipality, you are likely to incur some costs. For example, if the cost of 1000 gallons is $4, and your deionizer has a capacity of 10 gallons per minute, you may end up spending up to $58 on water bills per month. It is however important to note that the cost of feed water may vary depending on your region.

Regeneration Chemicals.

Demineralized water filter systems necessitate periodic regeneration in order to restore optimum exchange capacity. The most commonly used regeneration chemicals are hydrochloric acid (HCL) and sodium hydroxide (NaOH) whose approximate costs per lb. are $0.24 and $0.24 respectively. The cumulative expenditure on regeneration chemicals depends on the frequency of regeneration.

Electricity is necessitated to power the system’s control board and the feed water pump. If a KWh costs $0.10 and your demineralization system runs on 460V 3Ph, you are likely to fork out $35 to settle your monthly electricity bill.

Filter and Resin Replacements.

Over time, the ion exchange resins and the pretreatment filters wear out and a deterioration in performance is detected. Replacing a worn-out resin may cost roughly $38 per month. This is because a cubic foot of anion resin costs approximately $250 while a cation resin costs $100/ft3. Hiring an expert to replace the resins also attracts labor charges totaling approximately $150 per day.

Other operational costs incurred may include:

  • Waste disposal.
  • Pretreatment.
  • Labor.

With all elements factored in, the cost of generating deionized water using a water demineralization system on average is approximately $2.78 per 1000 gallons.

The System Features One Should Keep a Close Eye on.

When you are searching for a compatible and highly dependable deionization machine, it is paramount that you first scrutinize its primary components and specifications. Here is a brief discussion of the features one should examine before buying a water demineralization machine.

• Footprint and Design.

At present, there are only a few individuals, companies, or businesses endowed with vast spaces. Before buying a deionizer, it is crucial to examine its footprint, weight, and design in comparison to the available space. There are compact and lightweight demineralization systems specifically designed for small-scale applications and there are large systems developed for high-volume applications.

• Exchange Capacity.

Exchange capacity is typically expressed in Grains and it measures the volume of water stripped off dissolved ions. By understanding the quantitative demands of your respective application, you can easily establish the perfect exchange capacity for your application. We have varying demineralization systems endowed with distinct exchange capacities for you to choose from.

• Service Flow Rate.

Most buyers tend to overlook the service flow rate when purchasing water purification equipment. The service flow rate is a measure of the number of gallons your demineralization unit deionizes per minute. It is often measured in gallons per minute and it often varies depending on the system’s size and exchange capacity. Most deionization systems have service flow rates ranging from 0.5gpm to over 200gpm.

• Control Board Transmission.

Deionized water filters are often classified as manual, semi-automatic, or fully automatic. Automatic deionizers have Programmable Logic Control (PLC) boards, which allow one to pre-program instructions. They hardly necessitate human intervention hence they are quite labor-efficient. Demineralization systems with manual control boards necessitate on-hand physical supervision and they are pretty labor intensive.
