Locally Treatment

Geographic position, residential structure, available space, demographic trends, climatic conditions, share of use for commercial and tourism purposes, disposal situation for residues and many other factors - such as minimum legal requirements or budgets - influence the selection of a suitable wastewater treatment system. INNOCHEM has developed a standardized system that, due to its modularity and high capacity, can be adapted to nearly any requirement. Even temporary wastewater treatment as a transitional or seasonal solution can be realized.

Benefits at a glance

  • No investment and operational costs for central sewer system
  • Low energy consumption because hugh pumping stations are not necessary
  • Low costs for property due to small footprint and space requirement
  • Excellent effluent quality in compliance with the EU Bathing Water Directive
  • Reduction of costs for fresh water due to water re-use
  • Locally closed water loops (artificial groundwater recharge)
  • No freshwater squandering by water-borne sewer systems (use of vacuum draining systems)
  • Flexible choice of site due to prevention of offensive smell
  • Not visible treatment plant (housing)
  • Reduction of receiving waters pollution by spreading effluents
  • No environmental impact through sewer construction
  • No ground water pollution through leaking sewers
  • Freshwater savings of up to 80 %
  • Expansion capability (modular design)
  • Short erection time
  • High operational reliability due to self monitoring system
  • Fully automized operation with remote monitoring and control
  • Independent of communal infrastructure and political decisions
  • Legal certainty in regard to minimum requirement in the future

The special benefits really come into effect when excellent effluent quality is required. This is the case for bodies of water used for bathing as well as ecologically sensitive streams (little water, low dilution or rare species) and sensitive coastal bodies (shallow depths, low water exchange and high temperatures). If purified water is reused for irrigation purposes, for example, an enormous added value results.

Commercial areas all share similar requirements when it comes to wastewater treatment of hotel resorts, national parks, mountain stations and service areas, worker camps and military camps. The common denominator here is that all of these areas require technology that reacts to fluctuations in wastewater production and that do not allow odors to develop at any time.

Hotel resorts

Hotel resorts and camping sites characteristically produce fluctuating amounts of wastewater. Depending on the tourism season, it is not uncommon for the amount of wastewater to vary by a factor of 10. This requires a modular wastewater treatment plant that meets the demands of these fluctuations. INNOCHEM solutions allows modules to be switched on or off according to actual demand. Aside from this feature, the required space and prevention of odor are of central interest. Depending on the location of the campsite, basic transportability of the system may also be desired. Generally, a population equivalent of 80 is calculated per hectare of campgrounds. Each hotel bed is counted as one PE. In associated restaurants, three seats equal one PE.

National parks

The sensitive and invaluable surroundings within a national park require the superior standards of effluent quality and operational reliability provided by INNOCHEM. Even the smallest amount of solids or increased germ concentrations in the effluent could have catastrophic ecological consequences. Smooth operation must be ensured 365 days a year. This frequently requires redundancy in the design of the plant as well as double-wall containers. In addition, national parks are usually difficult to reach and should therefore be optimized with regard to handling residues. Naturally, this solution is not to be noticed in this environment with either the eyes or nose.

Worker and Military camps

The wastewater volume is produced within a few hours of the day. Experience has shown that the water should be buffered and successfully purified. It is of particular importance to ensure that the wastewater does not begin fouling and develop an unpleasant odor during storage. The total amount of wastewater can be estimated by calculating one population equivalent per sleeping unit. Worker camps such as those at major construction sites are usually operated for only one to two years. The operators of these small purification plants particularly prize the fact that the system can subsequently be used in another location for effective purification of wastewater and can once again supply high-quality process water for such things as the production of concrete.

In military accommodations, the required purification plant size is generally estimated by calculating one PE per bed. For a barracks with 1,000 sleeping units, a purification plant with a capacity for 1,000 PE or 150 m³ of wastewater per day should be planned. The germ-and solids-free effluent is suitable for washing vehicles or other equipment.

High-rise buildings & factories

Wastewater treatment requirements for large buildings and purification plants for operational staff are characterized by widely fluctuating amounts of wastewater. At industrial production sites, so-called sanitary wastewater should be treated separately if possible in order to prevent faecal contamination of the main water flow.

INNOCHEM offers modular wastewater treatment plants for offices and commercial buildings as well as residential properties. These plants are designed to meet these fluctuating demands and can be operated to adapt to actual requirements. Naturally, no space is wasted with an unnecessarily large purification plant. The ideal solution is a system that can be housed in the basement - and that eliminates the possibility of any unpleasant odor. INNOCHEM meets this requirement with extremely compact systems and highly effective concepts for preventing odors.

A rough estimate for the necessary size in an office property can be obtained by calculating one PE for every three employees. If the building houses common facilities such as a cafeteria, the calculating unit is lowered to two employees. Restaurants in an office building that are also frequented by external guests should be calculated with one PE for every 3 seats. Compact purification plants in office buildings with operate independently and reliably.

Continuous urbanization leads in many metropolitan areas to the construction of amazingly high buildings on very limited space. This leads to the increasing creation of cities within cities - with shopping, sport and dining facilities. In these artificially created microcosms, there is usually an independent electricity supply. It is frequently desirable to extend this independence to the water supply and disposal system. INNOCHEM has recognized this desire and offers a fitting solution.  

In residential buildings, the one PE is usually calculated per existing room in order to estimate the necessary size of the small purification plant.
