# Floating covers for food and beverage process water

Algae, evaporation, and emission control for food, beverage, brewing, and dairy process water. NSF-61 certified variants for direct contact.

NSF-61 certified hexagonal covers suppress algae, reduce evaporation, and cap odor emission on food
and beverage process water — supporting EU food-safety and emissions compliance.

## What covers do for food and beverage operators

Food and beverage operations rely on consistent water quality at multiple process stages: CIP
(clean-in-place) storage, cooling ponds, effluent treatment, brewing and dairy storage. Each
stage has different requirements; floating covers address the common surface-water issues —
algae, evaporation, emissions — without process disruption.

## Benefits

| Application | Benefit |
|---|---|
| CIP water storage | Algae suppression + reduced microbial load |
| Cooling pond | Evaporation and algae control |
| Effluent treatment | Odor and VOC reduction |
| Process hot water | Heat retention |

## How covers work in food and beverage applications

A NSF-61 certified HDPE cover on CIP, cooling, or process water reservoirs suppresses algae,
reduces evaporation, and retains process heat. Material is inert with respect to food-grade
contact; the surface is cleanable for routine inspection.

## When to use covers in food and beverage

- CIP water storage where microbial control reduces sanitisation chemical use
- Cooling ponds in drought-stressed regions
- Effluent treatment ponds (sugar mills, dairy plants, breweries) for odor compliance
- Hot process water reservoirs (brewing wort cooling returns, dairy CIP heat-up)
- Any operation reporting under CSRD water-disclosure

## Covers vs. alternative algae controls

For potable-contact applications, only NSF-61 certified materials are permitted. UV treatment is
common at point-of-use but doesn't prevent algae growth in storage; chemical dosing addresses
existing blooms but requires continuous monitoring. Covers prevent at the source — usually combined
with one downstream disinfection step for full compliance.

## Regulatory context

EU food-safety regulations require auditable water-quality processes. NSF-61 certification and
the documented lifecycle of the original patented hexagonal cover support that auditability.
