Meeting the precise needs of clients

Serving up to 2000PE  population equivalent (PE) the HiPAF sewage treatment systems is adapted to meet your specific needs, backed by continued dedicated technical support:

  • Upfront consultation to understand the specific needs of the project 
  • Dedicated technical support throughout the whole life of the project 
  • Meeting EA standards even at Sites of Special Scientific Interest (SSSI) 
  • Collaborating with the client to deliver cost-efficient treatment for the whole life of the plant 
  • Hire equipment to keep sites operational and within consent

Product highlights

  • Process guarantee for the lifetime of the plant
    - Minimum of 25 years design life

  • Energy saving timer – pulse air from the blower(s) into the process

  • Low operator maintenance

  • Manages variable flows and loads
    - Ideal for seasonal venues such as hotels, caravan parks and cafés. 

  • Compact & modular design options - to overcome site access and footprint restrictions

  • Scalable solutions to accommodate growing populations

Effluent quality

The HiPAF range can typically attain: BOD 10mg/l: SS 10mg/l: Ammonia Nitrogen 2mg/l (with tertiary treatment), however higher igher NH 4-N and BOD 5 removal is achievable. Option of phosphate removal is available with the use of additional process technologies.

Footprint and energy

The patented process (Hybrid-SAF biozone) has a 30% smaller footprint size than comparable technologies and has the added benefit of a built-in timer for the blower(s) which cuts the amount of energy used to treat effluent by up to 50%. 

Low maintenance

  • No odours due to a separate primary tank

  • No internal mechanical or electrical moving parts within the tank

  • Easier tankering - primary sludge and humus are stored together

  • Emptying of the tank not required during routine maintenance 

  • Midi and Modular - rectangular tank shape reduces dead zones 

Compliant

  • Compact HPC CE marked to BS EN 12566-3 - ideal for a Site of Special Scientifiic Interest (SSSI)

  • Midi and Modular designed to BS EN 12255-1/15 and manufactured using BS 4994 as a guide

  • British Water’s Code of Practice - Flows & Loads

  • UK Building Regulations

  • Environmental Agency guidelines

Design and manufacture

  • Below ground installation do not interrupt the landscape views 

  • Above ground installation – custom designed options 

  • GSM telemetry available for remote monitoring of the plant

  • Midi and Modular lids

    • Commercial applications - lockable large gas strut lids  

    • Water utility applications - MK3 lids with protective grate

  • Glass reinforced plastic (GRP) is UV stabilised with an external gel coat finish

  • UK manufacture in a quality controlled environment

Compact HiPAF HPC (1 up to 60 PE)

Applications

  • Domestic homes
  • Small business
  • Ideal for environmentally-sensitive areas

Site of Special Scientific Interest (SSSI)

Compliant to BS EN 12566-3

The compact HiPAF HPC uses no chemicals during the treatment process and is ideal for locations which need extra consideration such as a burn, nature reserve, fisheries, salmon river or close proximity to water extraction (well).

The HiPAF is also specified by the highly regulated UK water utilities and meets stringent European environmental discharge consent standards. 

 

 

 

Warranty

Warranty 25 years on the tank and standard air blower (housed in the kiosk) 2 years subject to correct installation, consistent influent conditions and regular plant maintenance as per the manufacturers’ instructions.

How the process works

Each HiPAF treatment plant includes a three-stage process – primary settlement, biological treatment (Hybird-SAF biozone) and final settlement.

Illustration-of-a-HiPAF-sewage-treatment-plant-for-off-mains-drainage

Stage 1 – Primary settlement 

  • Incoming wastewater enters the primary settlement stage where organic and inorganic matter settles
  • The sludge is held in this section until it requires de-sludging
  • A unique forward-feed arrangement uses an airlift to deposit wastewater into the biological treatment stage (biozone), which keeps peak flows from entering the system and prevents hydraulic surges

Stage 2 – Biological treatment

  • Settled liquor enters the biological section either by displacement or via the airlift
  • High-voidage plastic media, contained between two floors within the biozone, encourages the growth of bacteria and other organisms which treat the wastewater
  • Air required for the treatment process is delivered by air-blowers housed in a weatherproof kiosk
  • The air also helps to scour the media bed, preventing the filter from blocking
  • A series of diffusers installed beneath the media bed ensure an even distribution of air

The segmented biozone process chambers eliminate the risk of process short-cuts and mitigates risks associated with variable loads.

Stage 3 – Final settlement

  • The treated wastewater (final effluent) enters the final settlement section
  • Dead biomass (humus sludge) from the process settles out
  • An airlift automatically transfers settled humus sludge back to the primary settlement section for co-settlement
  • The final effluent is discharged through gravity displacement to either a watercourse or a sub-surface irrigation field 

Typical sector site applications

  • Animal waste options such as stables and kennels 
  • Agricultural growers and garden centres 
  • Caravan and camping, lodges and residential parks 
  • Custodial establishments 
  • Golf courses, fishing lodges and yacht clubs 
  • Hotels, restaurants and public houses 
  • Housing developments 
  • Motorway service stations 
  • Manufacturing – industrial trade effluent 
  • Care homes and retirement villages 
  • Commercial buildings and offices 
  • Schools, colleges and training centres 
  • Stately homes and large country estates 
  • Villages and rural communities 
  • Visitor centres 
  • Water utilities   
  • Zoos, theme parks and leisure attractions and leisure centres
