SWATER Mix: a Knowledge Based Simulator and Decisions Support software Tool, for Wastewater Treatment Plants
Bilingual Procedure (EN/IT) – S.I./U.S. Units Converter Tool (SWater add-on)
SWater Mix is an innovative software procedure to support design/up-grading, testing and simulation of urban/industrial and mixed wastewater treatment and/or equivalent. It is born to meet needs of “field”, allowing to verify, in all operative conditions, operational performance and the residual capacity of each of the different sections of the cleaning treatment (physical-chemical-biological). Its approach allows to consider “dimensioning and verification” like two “points of view” of a same object. That is to say the corrected functionality of the plant (or an existing project), in achieving the quality of continuity of the effluent, in accordance with local regulations. It can be used not only for urban wastewater, but also for industrial wastewater and a mix of them (urban-industrial compliant mixed).
The main peculiarities of the SWater software are:
- it is really able to foresee the quality of final effluent to compare law limits by using static and dynamic simulations (tested on more than five hundred wwtp);
- it deals with wastewater plants sized from 50 to over 5.000.000 equivalent habitants;
- it can be used not only for urban wastewater, but also for industrial wastewater and urban-industrial mixed;
- it can run with data input normally available (hydraulic load, pollution load, …);
- it is based on graphical and numerical simulation of the optimum operating conditions and on the use of process indicators for verifying the correct functioning of the plant;
- it allows to be used in design, in testing or in up-grading mode, at the same time, simply just clicking on a button;
- software interface “user-friendly”, so it can be used easily even by an operator with the basics of computer;
- it is able to develop a new sensibility in water management for professional operators
- it is able to get cost reduction of wastewater management at least by 18% (average);
- it produces Automatic Technical Reports in MS-Word! What else?
In spite of a large availability of existing math models available on market dealing with WWTPs Modeling, some of technical responsibles and operators have consistently complained a low applicability and flexibility to real way of working of treatment plants, in most of cases of these math models . Moreover, math modelling has largely been seen as an academic analysis, and so far from real water treatment plants effectiveness, infact they:
- are bound by strict and rigid math patterns, with fix generic parameters as “constants” “k” as from technical-scientific literature;
- have been made by theorist and not by workers, experts of processes;
- require some input parameters not covered in the analysis of routine checked in laboratories (for. Ex. Soluble COD, etc.);
- observe processes from one point of view, considering design and testing as two different approaches;
- are based on the graphically linking of model blocks, which represent unit processes (e.g. sewer section, primary treatment, activated sludge tanks).
SWater is based on an holistic approach, by analysing and testing wastewater processes. It is based on the integration of traditional deterministic mathl models (IAWPRC) and heuristic knowledge based softcomputing models related to wastewater processes. SWater has been made because between theory and practice there is a difference that makes really understand the goals of treatment, which represents the added value that all the operators require to a simulation software. The difference is not on theoretical principles of operation of treatment processes; even SWater’s code is derived by theoretical models ASM1/ASM2 (Activated Sludge Models developed by the International Water Association – IWA), as all the more influential existing computer codes on the market. The difference is in how the theoretical models are used, and not in their calculations. These algorithms are compared to the reality of wastewater treatment plants and the parameters that you have actually in the field and in the case of the project, both in case of testing and/or upgrading.
WATER LINE:
- PRELIMINARY: Screening, Grit Removal, Lifting, Equalization
- CHEMICAL-PHISICAL: Initial-Storage/Homogenization, pH, Neutralization, Coagulation-Flocculation, Chemical Precipitation, Final Homogenization
- PRIMARY: Primary clarifier, Air Flotation
- SECONDARY : Biological & Nutrient Removal, Secondary Clarifier
- TERTIARY: Emergy phosphorus chemical removal, Effluent Filtration, UV-C disinfection, Chlorination
SLUDGE LINE: AEROBIC /ANAEROBIC DIGESTION, THICKENING, POST-THICKENING, DEWATERING
So, SWater:
- gives possibility to interact at the same time or with the data of dimensioning, than of verification, because not bound to rigid mathematical models;
- doesn’t need to calibrate of the theoretical models “k” because it uses a heuristic approach (non deterministic), very close to actual operating conditions of real plants;
- has been realized to satisfy the needs of operators;
- uses operative data and input normally available (hydraulic load, pollution load, …);
- provides rapid analysis with minimum sustainable number of data input;
- considers design and testing as two point of view of the same target: a designed WWTP should satisfy its testing, and a tested WWTP should satisfy its design;
- identifies “working area” of each treatment section: a visual indicator detects the process efficiency parameters in their range-ability, in order to notify by “earlywarning” (near end-scale), a critical process-event in progress;
- provides global view information about the process;
- provides “just in time” information that guide the operator in selecting the most appropriate system solutions based on the real needs of field;
- provides to control the quality of the final effluent, continually;
- provides a trend behaviour of the treatment plants;
- provides statistic integration of hourly load data;
- doesn’t use a graphical layout for the design of the plant, and so it is easy to use even for non-designers;
- calculates both construction and operative costs, with reference to the algorithms used in action plans;
- provides a supply report automatically in Word format, which allows the operator to have clear and documented design and testing operations at the end of each operation.

Advantages and Innovation: SWATER is a flexible instrument that allows the matching between theory and practical experience. It is expected interdisciplinary integration (kinetics, biology, chemistry, etc.) between theoretical and practical methods, using artificial intelligence.
