Product Description

WATER&FOOD USE: Our Water flow restrictor is made from safe,non-toxic materials. They are widely used for Household Water Purifier ,Commercial Water Purifier ,Small reverse osmosis equipment,
 
SIZE&TUBE COMPATIBLE WITH: Fits standard 1/4 RO tubing used on most RO systems ( Check your tubing Size carefully before order);Household purifier you can choose 300cc/min-50Gallon;350CC/min-50Gallon/75Gallon;420CC/min-75Gallon;450CC/min-100Gallon;550CC/min-100Gallon/200Gallon; 650CC/min-200Gallon.For 400Gallon-800Gallon Commerical Water Purifier, you can choose 800CC/min, 1200CC/min or 1500CC/min,
 
Working Pressure: more than 8kg;Medium Temperature: 5~50 Centigrade;The ratio of product water to waster water is about 1:3,it's not fixed, it depends on the working pressure and water quality.
 
EASY INSTALLATION: Provides quick and convenient assembly-saving time&expense. New generation Non-Locking Clip technology offer an easy DIY installation without tools required.

What is it?
Our flow restrictor is made of food grade material,which allows users to connect and disconnect quick and easy without the need of any other tools.It is used to give you the most RO water for the least amount of waste water production.It's purpose is to create back pressure on the drain line to help push water through the membrane but flow fast enough to keep it clean. Our flow restrictor fits standard tubing OD 1/4" Copper, CPVC, PEX and PVC tubing for most RO systems
 
Where to use it?
Applications include RO system, beverage dispensing, refrigerator ice maker, coffee machine etc. This quick connect fitting goes on the waste water line to help restrict the flow and keep your membrane clean. A flow restrictor to balance the brine solution coming off of the membrane and insurance to make sure there was enough back pressure against the RO membrane for proper filtration. you can also used to upgrade your system due to increase usage. This will take the headache out of an water filter installation,
 
How to use it?
In the drain line that dumps waste water into the sink. So find the line hooked up to your sink drain and splice the flow restrictor in. There is an arrow on it to tell you what direction to connect it. To remove, just push in the outer circle on each end and pull right out. Just make sure your membrane flow rating matches this flow restrictor for best results. also You need to make sure the tubing is cut squared to insure no leaks. Be sure you cut the tubing even and straight, without crimping it. Then insert straight, and all the way into the connector. If it's crooked, or not inserted all the way, or crimped, it may leak.

FAQ

Q: Is 1*400GPD better than 2*200GPD?

A: 200GPD is better, there's less glue during production, better salt rejection rate and water flow.

 

Q: When to clean the membrane elments?

A: it is important to clean the membrane elements when any of the following conditions occur:

10-15% decrease in normalized permeate flow

10-15% increase in normalized permeate total dissolved solids (TDS)

10-15% increase in normalized pressure drop between feed and reject

 

Q: How to Solve RO Membrane Blockage?

A: 1. Firstly, you need to determine if the membrane of the home RO System is really blocked.

2. Understand the water quality in the region and see if the main components of scale are mainly composed of calcium and magnesium salts.

3. Dispense the syrup (10% hydrochloric acid) or the diluted detergent (descaling detergent on the market) and the special RO membrane cleaning agent according to the composition of the scale, and place the RO membrane therein for 24 hours.

4. Next, rinse the RO membrane after soaking, and rinse the RO membrane with water produced by ultrafiltration. When flushing, close the pure water outlet and open only the waste water outlet.

 

Q: Why the RO membrane is blockage after one to two months?

A: 1. raw water with high salt content, too many scales.

2. the content of organic matter in the water exceeds the standard, RO membrane is fouled and plugged

3. high RO film recovery rate

4. the purifier is not equipped with flushing function. After long-term use, high-concentration brine is deposited in the RO membrane shell.
