The use of an automatic on-line titration unit for monitoring the effluent quality of wastewater plants is presented. Buffer capacity curves of different effluent types were studied and validation results are presented for both domestic and industrial full-scale wastewater treatment plants. Ammonium and ortho-phosphate monitoring of the effluent were established by using a simple titration device, connected to a data-interpretation unit. The use of this sensor as the activator of an effluent quality proportional sampler is discussed.

An evaluation of the 24 existing pond systems for treatment of urban wastewater in Catalonia (north-eastern Spain) was conducted in 1997-1998. The evaluation covered 13 aerated ponds, 7 waste stabilization ponds (WSP), and 4 maturation ponds added to conventional biological wastewater treatment plants (WWTP). The technical characteristics of the pond systems were obtained through a survey completed during several visits to the plants. Performance data was supplied by the Catalonia Wastewater Agency and the monthly monitoring campaigns conducted during 12 months in five WWTP. The average ratio of water surface to population equivalent (p-e) is 1.3 m2/p-e for aerated ponds, 9.6 m2/p-e for WSP and 1.7 m2/p-e for maturation ponds added to conventional WWTP. Average electrical energy consumption is 0.5 kW.h/m3 for aerated ponds and 0.04 kW.h/m3 for WSP (when wastewater has to be pumped from the sewer). Most of the WSP show an inadequate level O & M, because the very limited operator attendance (0.6 h/dayon average) as compared to aerated ponds (3.2 h/day on average). Effluent quality of aerated ponds (31 mg SS/l and 22 mg BOD5/l, on average) is usually better that of WSP (100 mg SS/l and 67 mg BOD5/l, on average). Most of the WSP are overloaded, with only two of the pond systems receiving less than 50 kg BOD5/ha. Facultative WSP show a better performance than anaerobic WSP; anaerobic WSP have very high overloading conditions (with more than 250 kg BOD5/ha.d). Average effluent quality of all the pond systems studied comply with European Union standards.

Abstract This paper deals with wastewater treatment systems placed in motorway service areas (MSAs). In the years 2008-2009 eight of such facilities installed on the stretch of the A2 motorway between Poznań and Nowy Tomyśl were examined and analyzed. The system consists of a septic tank, a submerged aerated biofilter and an outflow filter. The volume of traffic on the highway was analyzed, the amount of water use was measured and peak factors were calculated. On this basis it was concluded that the inflows to the wastewater treatment systems in many cases exceeded the nominal design values. Based on the analysis of effluent quality it was found that the effects of plant operation in large part did not meet the requirements. It was found that the bioreactor aeration system and the design of the suspension separator (outflow filter) should be modified. One of the solutions was to use the soil-reed bed for wastewater treatment. The treatment of wastewater from the MSAs is a task that must take into account the unusual character of these facilities and the atypical quality of the effluent.

Wastewater Use

As a study of the proposal of a tertiary system for the improvement of the effluent quality of the wastewater treatment plant of the municipality of Jilotepec, the implementation of strategies has been sought, in order to achieve a qualitative research method, focusing on design and mathematical calculations, of wastewater use. To this end, the objectives are to carry out a research methodology proposed to analyze the arrangement of the aerators within the position of the Imhoff-type aerobic reactor, thereby achieving an acceptable sedimentation process, and subsequently to change the position of the aerators within of the aerobic reactor achieving a more complete cleaning to allocate the effluent for irrigation under the parameters of NOM-001-SEMARNAT-1996, looking for a better quality of effluent, with destination of urban use and as a calculation strategy it was proposed to implement a process of phytoremediation to avoid possible damage to the effluent
