LF‑XULP‑8040 Ultra‑Low‑Pressure Reverse Osmosis Membrane Element For Rural Community Groundwater Desalination

Product Overview

Many rural and community water‑supply projects face raw‑water with low total dissolved solids, but conventional RO elements require high pump pressure leading to high power‑consumption. reverse osmosis membrane element LF‑XULP‑8040 belongs to the product portfolio under Water Filter Element. This ultra‑low‑pressure aromatic polyamide composite RO membrane achieves stable salt rejection performance at only 100 psi operating pressure, cutting system energy consumption by nearly 30% compared with traditional brackish‑water RO elements. It targets raw‑water TDS below 500ppm, for village centralized drinking‑water, campus water station and small‑scale food‑processing water‑making scenarios.

Basic Technical Parameters

Typical Project Application Scenarios

LF‑XULP‑8040 is optimized for low‑salinity raw‑water projects. In rural community water‑supply projects, shallow well‑water with TDS 200‑450ppm can obtain qualified drinking‑water without equipping high‑pressure heavy‑duty pumps, reducing equipment investment and long‑term electricity cost. It is also applied for small‑size bottled‑water production lines and campus centralized purified‑water station. This membrane element must be matched with pre‑treatment security filter, you can select High Flow Filter Cartridge as security‑filtration consumable to reduce SDI value of feed‑water and protect RO membrane surface. Different from BW‑series high‑salt‑tolerant RO, XULP‑series is not fit for high‑salinity brackish‑water.

Core Product Advantages

Optimized composite polyamide separation‑layer realizes high water‑flux under ultra‑low operating‑pressure, lowering requirement for high‑pressure pump and pressure‑vessel pressure‑bearing grade. Stable salt‑rejection performance for surface‑water and shallow‑well‑water source. Strict dimensional tolerance, fits standard 8‑inch RO pressure‑vessel housing for direct drop‑in replacement. Each element will complete flux and salt‑rejection inspection under simulating test‑condition before factory‑delivery. Reduce system operating‑cost for decentralized water‑supply EPC projects. For auxiliary fluid‑handling equipment selection, please refer to Oil Filtration Machine series for reference of filter‑consumable QC‑management standard.

FAQ

Q1：What kind of raw‑water is LF‑XULP‑8040 suitable for?
A1：Mainly for raw‑water TDS below 500ppm: surface‑water, shallow‑ground‑well‑water, municipal tap‑water; not applicable for brackish‑water and high‑salinity wastewater.

Q2：Does LF‑XULP‑8040 need special pressure‑vessel?
A2：It adopts standard 8040 dimension, can be installed in ordinary 8‑inch RO pressure‑vessel without housing modification.

Q3：What pre‑treatment should be equipped before this RO membrane?
A3：Need multimedia filtration, activated‑carbon filtration plus security filter‑cartridge, guarantee feed‑water SDI15 ≤5.0, free‑chlorine＜0.1mg/L.

Q4：What is the main difference between XULP‑series and ULP‑series RO membrane?
A4：XULP works under 100psi ultra‑low‑pressure; ULP‑series test‑pressure is 150psi, fits raw‑water TDS up to 2000ppm.

Q5：Can you provide complete‑set membrane‑selection scheme for community water‑station project?
A5：Yes, please provide raw‑water test‑report, system design water‑yield requirement for our technical evaluation and proposal.
