Product Description

WATER & FOOD USE: Our cutting-edge water flow restrictor is crafted from safe, non-toxic materials, ensuring peace of mind. Perfectly suited for a variety of applications including Household Water Purifiers, Commercial Water Purifiers, and Small Reverse Osmosis Equipment, this product meets the highest standards of safety and efficiency.

SIZE & TUBE COMPATIBLE WITH: Designed to seamlessly fit standard 1/4 RO tubing, our product is compatible with most RO systems. Pay close attention to your tubing size before ordering to ensure a perfect fit. For household purifiers, choose from options like 300cc/min for 50Gallon systems, to 650CC/min for 200Gallon systems. For commercial water purifiers ranging from 400Gallon to 800Gallon, we offer options like 800CC/min, 1200CC/min, or 1500CC/min, catering to all your needs.

Working Pressure: Engineered to withstand more than 8kg of pressure, with a medium temperature range of 5~50 Centigrade. The product-to-waste water ratio is approximately 1:3, adaptable based on working pressure and water quality, ensuring efficiency and reliability in various conditions.

EASY INSTALLATION: Experience the convenience of quick and hassle-free assembly that saves both time and costs. Our innovative Non-Locking Clip technology empowers you to achieve a DIY installation effortlessly, without the necessity of any tools.

What is it?
Our flow restrictor, crafted from premium food-grade material, allows for seamless connections and disconnections without the need for additional tools. Its primary function is to maximize RO water production while minimizing waste water. It creates back pressure on the drain line, aiding water passage through the membrane, and operates efficiently to maintain membrane cleanliness. Compatible with standard 1/4" tubing, including Copper, CPVC, PEX, and PVC, it suits most RO systems.

Where to use it?
Ideal for a multitude of applications, including RO systems, beverage dispensers, refrigerator ice makers, and coffee machines. This quick connect fitting is designed for the waste water line, ensuring efficient flow restriction and membrane cleanliness. It balances the brine solution and guarantees adequate back pressure against the RO membrane for optimal filtration. Perfect for upgrading systems due to increased usage, it simplifies water filter installations.

How to use it?
Locate the drain line that directs waste water into your sink and splice the flow restrictor in place. An arrow on the product guides correct directionality. For removal, simply press in the outer circle on both ends and pull out. Ensure your membrane flow rating aligns with the flow restrictor for peak performance. Properly cut tubing to avoid leaks—make cuts straight and even, avoiding crimps. Insert tubing completely straight into the connector to prevent leaks.

FAQ

Q: Is a single 1*400GPD system superior to a dual 2*200GPD setup?

A: Opting for the 200GPD system is advantageous due to reduced adhesive use during production, which enhances the salt rejection rate and boosts water flow efficiency.

Q: When should membrane elements undergo cleaning?

A: It is crucial to clean the membrane elements when experiencing any of the following conditions:

A noticeable 10-15% reduction in normalized permeate flow.

A marked 10-15% increase in the normalized permeate total dissolved solids (TDS).

A significant 10-15% rise in the normalized pressure drop between the feed and reject streams.

Q: What are the steps to resolve RO membrane blockage?

A: 1. Begin by confirming whether the home RO System's membrane is genuinely obstructed.

2. Assess the regional water quality, particularly if the primary scaling components are calcium and magnesium salts.

3. Prepare a solution using 10% hydrochloric acid or a diluted market-available descaling detergent, along with a specialized RO membrane cleaning agent, based on the scale composition. Immerse the RO membrane for 24 hours.

4. Subsequently, rinse the RO membrane following the soak, utilizing ultrafiltration-produced water. During this process, ensure the pure water outlet is closed and the wastewater outlet is open for effective flushing.

Q: Why does RO membrane blockage occur within one to two months?

A: 1. High salt content in raw water results in excessive scaling.

2. Elevated organic matter levels in water surpass standards, leading to RO membrane fouling and blockage.

3. The RO film exhibits a high recovery rate.

4. The purifier lacks a flushing function, causing long-term high-concentration brine deposition in the RO membrane shell.
