HL-CONT Compact Sewage Treatment Plants
HL-CONT Compact wastewater treatment plants are optimized for the common operating scenarios of units with a capacity of up to 3000 liters/day in the maritime industry.
They offer maximum performance and reliability in the smallest and lightest package.
As a true HAMANN wastewater treatment plant, the HL-CONT Compact has a stainless steel construction of the highest standard and the highest quality components throughout.
This unit covers all the essential tasks of a wastewater treatment plant as part of the on-board wastewater system, and it does so in a truly compact package at a lower cost.
KEY FACTS - HL-CONT Compact
OPTIMISED PACKAGE FOR BASIC SCENARIOS
HL-CONT Compact plants are optimised for the most common operating scenarios in their class.
They offer the renowned HAMANN performance and quality at a lower cost.
EXTRA SMALL & LIGHT WITH ADAPTABLE LAYOUT
The HL-CONT Compact 0125 is the smallest and lightest sewage treatment plant with these performance characteristics and full IMO, EU-MED and UK-MER certification available on the market.
It can be set up in two different layouts to suit different mounting positions.
COMBINED BLACK WATER & GREY WATER TREATMENT
As all HAMANN plants, the HL-CONT Compact systems are designed to treat black water and grey water as a sewage mixture in the same process.
This benefits the performance and reliability of the sewage treatment system as well as the environment.
EASE OF OPERATION & LOW MAINTENANCE
Routine functions on HAMANN plants are fully automatic and no specialised skills are required to operate them.
The technology eliminates the need for filters and membranes, which would require a lot of work for regular cleaning and replacement.
Routine maintenance on HAMANN plants can be carried out quickly and easily by the crew on board as the open design allows instant access to all components for inspection and service purposes.

TWO LAYOUT OPTIONS - HL-CONT Compact
The HL-CONT COMPACT 0125 sewage treatment plant, or marine sanitation device, is available in two alternative layouts, giving even more flexibilty for installation:
Layout A with shorter width but more depth and
layout B with minimum depth, e.g. for mounting on walls.
On delivery, all units are set up in layout A and can be quickly and easily converted by the customer if desired.
SEWAGE TREATMENT TECHNOLOGY - HL-CONT Compact
PREPARATION: CREATING THE SEWAGE MIX
HAMANN HL-CONT Plus sewage treatment plants are designed to process both blackwater and greywater as a sewage mixture.
This mixture is created in the sewage mixing tank from which it is pumped into the sewage treatment plant.
Depending on the tank configuration on board, greywater and/or blackwater are transferred into the sewage mixing tank to create the sewage mixture.
When the filling level in the sewage mixing tank reaches a predefined level, the feeding pump of the sewage treatment plant starts to operate and the treatment process is initiated.
MACERATION
The sewage mixture from the sewage mixing tank is first run through a macerator to chop up solid and fibrous components.
TSS/COD/BOD REDUCTION
By means of their Dissolved Air Flotation (DAF) technology, HAMANN HL-CONT Plus sewage treatment plants separate the suspended solids (TSS) and reduce the chemical (COD) and biological (BOD) oxygen demand.
The sewage is enriched with air under a pressure in the saturator.
After being discharged into the flotation tank through the pressure release valve, the excess air forms micro bubbles.
A flocculant is added in order to let air bubbles and susupended particles form larger flakes. These flakes float upwards, creating a sludge foam on the surface and leaving the clear phase in the lower part of the flotation tank.
The sludge foam spills into the sludge compartment and is subsequently fed into the ship‘s sludge tank.
DISINFECTION
The already largely purified sewage is finally exposed to UV radiation to degrade the DNA of bacteria and microorganisms, rendering them incapable of reproducing and infecting.
After this finishing step, the treated sewage from the HAMANN HL-CONT Plus sewage treatment plant is safe to be discharged overboard (if permitted).
