Cutting-edge Membranes

Cutting-edge Membranes | Water Purification | Plumbing | Bristol

Imagine crystal-clear water flowing straight from your tap, stripped of impurities by the same advanced technology trusted in laboratories and spacecraft. HEP brings that future to Bristol today, harnessing ultra-fine membrane plumbing to capture sediments, chemicals and even microscopic pathogens before they ever reach your glass. The result is pure taste, better appliance longevity and the peace of mind that comes from next-level water purification without bulky add-ons or constant filter swaps.

Backed by local engineers who know the city’s pipework inside out, our systems slot neatly into new builds or retrofits, cutting energy use while protecting the planet. Whether you’re a homeowner seeking healthier hydration or a business chasing sustainability targets, HEP’s tailored installations and 24/7 support turn everyday water into a high-performance asset. Discover how effortless purity can be—right here in Bristol.

FAQs

What is a membrane-based water purification system and how does it work?

A membrane system forces water through a semi-permeable barrier with microscopic pores (down to 0.0001 µm). Under pressure, pure H₂O molecules pass while dissolved salts, heavy metals, microorganisms, micro-plastics, and other contaminants are rejected and flushed to drain. Our Bristol installations typically combine several stages—pre-filtration, high-performance reverse osmosis (RO) or nanofiltration (NF) membranes, and post-carbon polishing—to deliver bottled-quality water straight from the tap.

Why should I choose membrane technology over conventional carbon or cartridge filters for my Bristol property?

1. Broader contaminant removal: Membranes capture viruses, pharmaceutical residues, and PFAS that standard filters miss. 2. Consistent performance: The pore size is fixed and does not enlarge with use, so removal efficiency stays high for years. 3. Space-saving integration: Our ‘membrane plumbing’ can be integrated into existing pipework—no countertop units cluttering kitchens. 4. Lower lifetime cost: Although the upfront price is higher, element lifespans of 3–7 years and minimal chemical usage lower total ownership cost. 5. Local suitability: Bristol’s moderately hard water (around 260 mg/L CaCO₃) benefits from RO-level softening, reducing limescale and prolonging appliance life.

Which contaminants will the system remove, and what water quality can I expect?

Lab testing at 60 psi shows ≥ 97 % rejection of dissolved salts (TDS), 99.99 % removal of bacteria (E. coli, Legionella), 99 % lead, arsenic, copper, and fluoride removal, plus virtual elimination of odour-causing chloramines used by Bristol Water. The delivered permeate typically measures 5–25 ppm TDS—comparable to premium bottled waters—with a fresh, neutral taste and no limescale formation.

How often do membranes need maintenance or replacement?

• Pre-filters: change every 6–12 months (depending on incoming turbidity). • RO/NF membrane element: 3–7 year lifespan in Bristol’s feed water, thanks to our anti-scaling pre-treatment. • Sanitisation: quick annual flush with food-grade peroxide. Our service plans include remote TDS monitoring; when rejection falls below 90 %, we schedule a site visit and swap the membrane in about 45 minutes.

What are the typical installation costs and are there any local incentives?

For a domestic under-sink system the turnkey price in Bristol starts at £695 + VAT; whole-house units range from £1,850 to £4,200 depending on flow rate. Commercial cafés/breweries pay £6,000–£25,000 for high-capacity units. Under UK Enhanced Capital Allowances, eligible businesses can deduct 100 % of the investment in year one. Bristol City Council’s Green Homes programme occasionally offers grants for efficiency upgrades—ask us for current availability.

Are membrane systems environmentally friendly?

Yes. The latest membranes operate at up to 85 % recovery, meaning only 15 % of feed water is discharged as concentrate—far lower than older RO units. Energy consumption is 0.2–0.4 kWh per 1,000 L, similar to running an A+++ fridge. All spent membranes are collected under our WEEE-compliant recycling scheme and re-purposed as industrial UF cartridges, keeping plastic out of landfill and supporting Bristol’s circular economy goals.
